It’s “United we Stand” and that one is shaping up to be one of my favourites.
The one you’re referring to is his earlier work, “Divided we Fall”, which is quite good but I personally really, really like being able to customize and define my mc.
Then again I ended up here because I was trying to find games with a gay male protagonist I could relate to and have since been spoiled by CoG to the point where I prefer to create my own mc’s.
Too bad US Navy regulations don’t dictate male divers wear speedo’s most of the time. 
a) People change. b) If they’ve got PTSD and/or after a particularly hellish or senseless battle I can imagine such a thing could happen. It’s not used lightly however if you go for a serious tone. If you go for stuff like “Blackadder goes forth” that again changes things.
